4 claims. (o1. 2in- 3.15)

to be easily and conveniently assembled with other preformed members into a tight, solid booth structure.

With the above and other objects in view, one embodiment of the invention presents a floor structure for a telephone booth or the like comprising `a frame unit of sheet metal in combination with a oor unit proper of plywood or other analogous laminated rigid material, supported on the frame but independently preconstructed. The frame unit in its preferred form comprises a substantially U-shaped principal member having an upstanding peripheral flange to abut against and be attached to appropriate wall units which stand on the rim of the floor unit which is supported by horizontal inwardly extending flanges of the U member. One or more tie members of sheet metal extend across the U and are attached as by welding to the horizontal flanges. Vertical cove and curb members, preformed of plywood or of plastic material rest on the floor unit and abut against the wall units. All these various units and members are preformed for `shipment and assembly without any cutting or alteration.

Other objects and characteristic features of the invention will lappear from the following detailed description of one embodiment thereof taken in connection with the accompanying drawing in which the same reference numerals are applied to identical parts in the several iigures and in which Fig. 1 is a broken View in perspective of the lower portion of a telephone booth or the like constructed in accordance with the invention;

Fig. 'I is a sectional view of a third form of 55 curb;

,-Fig. 8 is a sectional View of a modified form of cove, and

Fig. 9 Vis a sectional view of a third form of cove.

Inthe principal embodiment herein disclosed, 5 there isprovideda metal vframe 20 of substantially rectangularly IU-shaped'form'having hori-` zontal inwardly extending flanges 2| and vertical peripheral flanges 22. One or more cross ties 23 of sheet metal extend across' the U and are at- 1o tached to the under surfaces of the horizontal anges 2| preferably by welding. The horizontal flange 2| at the rear is formed with two or more downwardly extending foot portions 24 whose bottom faces are in the same plane as the under l5 surfaces of the cross ties 23.

A preformed floor unit 25 is supported on and bridges across the flanges 2| and the cross ties 23. This iioor unit is preferably made of a single piece of plywood which is light in weight, rigid, 20 A strong and non-warping. As shown here, this floor unit 25 comprises three laminas but is not limited to this number. The under surface of the bottom lamina rests on the top surface of the cross ties. Along the sides and rear, the 25 under surface of the rim of the floor unit is cut away to receive the flanges 2|, and expansion spaces 26 are provided to allow for expansion of the plywood with atmospheric changes.

The wall units 21 of the booth are footed on the iioor unit 25 preferably just within the vertical flanges 22 and are recessed to receive the flanges as shown. A cove member 28 of suitable form is placed on the floor unit abutting against the inner side of the foot of the wall and supports a curb member 29 of appropriate form. The cove and the curb may be of any suitable material. As shown in Figs. 3 and 4, the cove is of solid wood, and the curb of plywood. In Fig. 7 is shown a sectionof a unitarily prenrolded combined cove and curb 3| of plastic material. The construction disclosed in Figs. 6, 8, .and 9 are self explanatory and need no detailed description. 45

Returning now to Figs. 1, 2, 3, and 4, a wearing surface layer 30 of linoleum, or of a moldable composition, or other appropriate material is laid on and conformed to the curbs, coves and floor. This may be held in place if necessary by nails or screws 32, and the vertical seams in the corners may be lled with an appropriate cement.-

As an alternative construction the wearing surface 30 may be a complete preformed member of sheet metal. or of other rigid or tough semirigid material such as cellulose acetate, artificial resin, or the like.

A preformed sill 33, preferably of a non-corfroding alloy such as brass or bronze or the like is attached to the front cross tie 23 by rivets or bolts 34, and is recessed along its rear edge to overlap and hold down the front edges of the Amembers 30 and 25 as best shown in Fig. '7.

If desired, the material of the sill may include grains of an abrasive material such as carborundum to obviate any slipperiness due to Wear, moisture, or the like causes.

It will be noted that the oor unit 25 is a sell sustaining bridge across the spaces dened by the arms of the frame and the cross ties 23, being supported by the frame at the edge portions of the floor unit only and at spaced intervals by the ties.

By the construction disclosed all the elements and units can be preformed complete and shipped to the proposed site of the structure and there joined and erected without any fitting or making.

The embodiments of the invention herein disclosed are illustrative merely and may be widely departed from without departing from the spirit and scope of the invention as pointed out in and limited only by the appended claims.

What is claimed is: 1. In a floor structure for telephone booths and the like, a unitary U-shaped frame, and a oor member of plywood supported thereon at the edge portions only of the floor member.

2. In a floor structure for telephone booths and the like, a unitary U-shaped frame, a oor member of plywood supported thereon at the edge portions only of the floor member, and a curb supported on the oor member.

3. In a floor structure for telephone booths and the like, a unitary U-shaped frame, a floor member of plywood supported thereon at the edge portions only of the oor member, a curb supported on the floor member, and a wearing surface member supported on the curb and the oor 4 member.

4. In a iioor structure for telephone booths and the like, a unitary frame of sheet metal comprising a U-shaped principal member having horizontal inwardly extending anges and a cross tie of sheet metal attached to opposite flanges, and a oor member of plywood resting on the cross tie and recessed to rest at the edge portions only of the oor member on the flanges.
